Patented sept. 2o, 1910.

i 4"To'all whom iti/may concern:

Be it known that i IIigh Point, in the State of North Carolina, have invented cerl.tain new and useful Improvements in a .i Flushing Mechanismfor Closet-Tanks; and

ineen of the United county of I do declare the following to be a full, clear,

fand exact description of the invention, such T10 as,` will enable others skilled in the art to i which it appertains to make and use the saine.

This invention relatesto flushing `mechanisms for closet tanks, and has especial reference to automatic mechanism for closing the outlet valve and refilling the tanks, such A as are illustrated in my prior Patent, No.

a simple, easily constructed, and positively One object of my invention is to provide actuated mechanism adapted,to automatically trip the catch upholding the outlet valve during allow the valve to close.

A further object provide means whereby therotation of the outlet valve may be effectively i prevented,

FigQQ is a transverse section. taken on the line 2-2 of Fig.` 1 showing'the operating. mechanism dropped to allow the outlet valve to close;` Figa?) is a similar ,view showing the outlet valve in plan view of other parts. Referring particularly to the drawings,

"the ,numeral 1 designates` a flush tank to which is connected the usual'water `supply e Zhaving arranged in suitable position an inlet valve 3 `which is automatically con- I, J oiiN S. WELBonN, a` States, residing atY Guilford and end a handle,

which inlet valve is connected to open or close the A suitable through the operating rod 5.

discharge pipe as 6 is arranged substantially central of the bottom of the tank and a valve seat 7 is arranged at the top of said discharge pipe, extending within the flush tank 1.

My improved flushing mechanism is adapted to operate with the discharge pipe 6 and the inlet pipe 2 by means of the mechanism to be hereinafter described.

An outlet valve 8 comprising a tubular body portion projects upwardly in the tank to a height corresponding with the up er surface of the water when the tank is il ed. In the upper and lower` ends of the tubular body portion of the valve are arranged apertured guide bars or spiders 10 which are slidably engaged upon the supporting or guide post 11, the upper end of which is secured in a suitable bracket 12 fastened to the upper rear edge of the tank, and the lower edge ofwliich is secured in a cross bar 13 arranged across the discharge pipe below the valve seat 7. On the lower end of the tubular body portion of the valve is suitably arranged a rubber packing ring or gasket 111, which, when the valve is in closed p0- sition, is adapted to form a fluid tight engagement with the valve seat 7, thus pre-l venting the discharge lof water from the tank. -The upper and lower ends `of the tubular body portion 4of thel valve are open to allow the water within the flush tank to escape through said outlet valve in the event that the inlet valve 3 is not entirely closed and thus preventingthe tank from overflowing at any time.

Pivotally mounted in a suitable position upon the tank is a valve operating lever 15 which is connected by means of a link 16 with an apertured projecting lug or ear 17 upon the upper end of the outlet valve, whereby will be lifted to allow the flushing Water to discharge. Any suitable means may be provided for rocking or actuating this lever 15, said means being herein shown as comprisin a munted in the front wall of the tank above the water level and has secured on its outer as 19, and on its inner end ya circular plate or disk 2() upon which is eecentrically mounted a rearwardly extending short shaft 18` which is pivotally when said lever is rocked the valve Integrally formed upon the bracket 12 ad-A jacent the guide or supporting post 11 and depending therefrom are spaced parallel guiding members 23 and 24,.the foremost of which, as 23, is extended laterally to some distance beyond the outer edge of the rearmost guide 24 to provide a wall 25 against which thenpholding catch 26 is adapted to engage, so that said catch will be normally retained in an operative position to automatically hold the outlet valve in its raised position. The catch 26 as herein shown is preferably formed upon the depending arm 27 of a lever 28 which is pivotally mounted, as at 29, upon the bracket 12 directly above the spaced guide members 23 and 24. The catch 26 may be of any desired shape or conformation, and preferably consists of the Vflat or locking edge 30 and the inclined lower vedge 31, the functions of which will be hereinafter more fully set forth. The lever 28 tures 37 in any ing the inlet valve 3,

tion of the outlet valve is preferably formed with a weighted, depending arm 32, and a forwardly extending arm or connecting bar 33, adjacent the forward end of which is provided a laterally extending pin or stud 34, by means of which the lever is pivotally connected to the tripping or actuating bar 35. This tripping or actuating bar 35 preferably comprises a body portion 36, extending substantially parallel with the out-let valve 8, in which adjacent its upper extremity is formed a plurality of adjusting aper of which the stud or pin 34 upon the lever 28 may extend. The lower end of the tripping or actuating bar 35 is bent or flanged, as indicated at 38, said flanges yprojecting' laterally in opposite di-' ends of the arms or flanges 38 contactingv with the side'of the tank whenever the movement of the water or other means causes the tripping or actuating bar to move.

The operating rod 5 connecting the float of the actuating means for opening or closextends between vthe body portion 36 of the tripping or actuating bar and the periphery so that it is guided in its` upward and downward movements to open or close t-he inlet valve In practice, when it is desired to discharge the kwater from the flush tank, the handle f 19 isrotated to rock the actuating lever 15 whereby the outlet valve 8 is lifted in the of the tubular .por-

manner hereinbefore described, bringing the laterally-projecting catch laterally to rock the lever 27, the weighted arm 32 serving to return the catch to its former or normal position immediately upon the passage of said lug or stud beyond the catch 26, said lug thereupon resting upon the flattened upper edge 30 of the.

neath the laterally extending lug 40 upon the upper end of the outlet valve, allowing said outlet valve to dro ring or gasket 14 into valve seat 7 and closing the outlet pipe. The downward movement of the float 44 andthe operating rod 5 serves to open the inlet valve 3 to allow the refilling o f said flush tank through the inlet pipe 2. It willbe apparent that as the water enters the flush tank the float 4 will be automatically lifted and will close the inlet valve after suflicient Water has been admitted into the tank.

From the foregoing description taken in` connection with the accompanying drawmembers depending from said bracket, one f of said guide members being extended toa point beyond the outer edge of the other of said guide` members, a lever pivotally mounted upon .said bracket above said parallel guide members, said lever vhaving a weighted rear arm and a depending catch adapted normally to extend across the'space between the guide members and contacting with the extended portion of the extended guide member, a tubular outlet valve having a laterally projecting lug adjacent its upper rounded lug or stud 40 into engagement with the inclined lower edge 30 of the catch 26, thereby forcing said thereby rockingthe lever 27 to release .the catch 26 from bedefined in the ap` .9 O ,bringing the p ackng engagement with the ioo end adapted to eXtend between said parallel guide members and engage said catch, and a tripping bar adjustably connected to the forward end of said lever to release said catch, said tripping bar being formed with laterally projecting flanges adjacent its lower end.
